TUBING SUPPORT.

Application filed July 20, 1927. Serial No. 207,192.

My invention relates to casing heads for slidable in said opening 13 tocompress and oil wells and has for its principal object to retain thepacking element or oil saver 14 provide a device of that characteradapted against the shoulder 12 and in contact with for performing theusual functions of a casthe tubing.

y The elements being assembled as described, with the casinghead securedto the casing, tubing may be lowered into the casing through the head inthe usual manner and while the tubing is then held suspended, thepacking element 14 may be positioned in the opening of the casing head,the supporting ring 33 resting on the seat 12 and the packing ring l tand retainer ring 34 installed therecap mem therein by the slips,sufficiently to permit the removal of the packing element andapplication of a standard elevator.

It is to be noted that the opening 20 in the gland orspider member is ofsuflicient diameter to permit passage of the tubing collarstherethrough, and that when the device is employed as a spider, theflanges 25 and 26 of the cap member may rest upon the flange 27 of thebody member.

What I claim and desire to secure by Letters Patent is:

A tubing support including, in combination with a casing head includinga top flange upon.

The mated packing gland members may then be assembled around the tubingand secured together by the bolts 31, and the assembled structurelowered into the opening :13 of the casing head so that'the lower endofthe gland collar rests upon the upper ring 345 of the packin element.The bolts 28 may then beinstalle in the flanges 25 and 260i the glandand flange 27 of the casing head and tightened to the extent desired toconfer the the gland on the packing to force the pac 'ng into sealingcontact with the tubing. The slips'22 may then be inserted in thetapered seat 21 to grip and retain the tubing when the latter isreleased from the elevator.

When the tubing is anannular flange mating with the casing head flange,a control collar having portions ex-. tending above and below the flangeto provide slip seat and gland elements, and lateral arms integral withthe flange and upper collar portion, and having bail hooks at theirouter ends, the cap member being divided to permit mounting flange,collar and arm members, and means for securing said members together andto the casing head flange.

In testimony whereof I aflix my signature.
